Device for extracting water droplet from ambient air

Abstract

The present invention provides an atmospheric water generator for extracting water droplets from ambient air which includes an insulating substrate, a plurality of electrode film units, and a liquid crystal / polymer composite film. Each of surface regions of the liquid crystal / polymer composite film has a plurality of liquid crystal molecules each having a hydrophilic functional group and a hydrophobic moiety. Each of the surface regions normally has one of hydrophilic and hydrophobic properties. When a voltage is applied to one of the electrode film units, the respective surface region is switched to have the other one of hydrophilic and hydrophobic properties, to thereby allow the water droplets condensed from the ambient air to move on the surface regions.

Description

technical field [0001] The invention relates to a water collection device, in particular to a water collection device for capturing water droplets from ambient air. Background technique [0002] Due to the increasingly severe climate extreme changes and population increase, the usable water resources on the earth are facing a crisis of shortage, which will cause problems such as food shortages and disease outbreaks. In order to solve the problem of water shortages, there are currently many different methods. type of atmospheric water collection device. [0003] General atmospheric water collection devices can be roughly divided into two types: condensation type and dry type. The condensing water collection device uses the heat exchange system to cool the air, or uses the low temperature environment provided by the soil to cool the air, so that the water vapor in the air can be condensed and collected, but if the condensing water collection device needs large-scale water col...

AI Technical Summary

Problems solved by technology

The condensing water collection device uses the heat exchange system to cool the air, or uses the low temperature environment provided by the soil to cool the air, so that the water vapor in the air can be condensed and collected, but if the condensing water collection device needs large-scale water collection, it must consume quite a lot Multiple energy sources, and the device is complex and difficult to install

The dry water collection device uses the deliquescence of special salts to absorb moisture in the air, and then uses the purification system to obtain clean water, but the dry water collection device not only needs to consume energy to filter out the salt in the water after collecting water, but also The technical threshold is high, so large-scale and energy-saving water collection is not possible

In addition, there is also a device that uses special fiber mesh materials to collect mist and dew, but it must have a better water collection effect in areas with large temperature differences between day and night and high humidity, and the subsequent collection process must rely on gravity effects to achieve water collection efficiency. bad
